Shot Blasting & Shot Peening Equipment

Automated Shot Peening Machines
Shot peening is used to finish metal parts that require increased wear and fatigue properties. In the process, shot bombards the metal part, creating small dimples in the surface.

Transmission Gears for EV & Combustion Engines
Ring and pinion gears are complex that must be finished with exact and uniform peening throughout the entire gear.

Ring & Pinion Gear Shot Peening Machines
Single cell peening machines are used to provide finishing and deburring for light to medium volume operations.

Single Cell Machines
Single cell peening machines are used to provide peening for light to medium volume operations. Used for parts ranging from small gears to large gears, single cell blasting machines offer precision peening using a wide range of media.

Swing Door Machines
Grit blasting is one of the most effective methods used to prepare surfaces for finishing.
